Just had a shitty message from an old school friend asking why I didn't turn up to her wedding last weekend.
Turns out her now husband had sent me a message on Facebook inviting me to the reception in my home town a week before the wedding. I didn't get notified about this message at the time, I think because I am not friends with the husband on there (I checked with DP to see if he had seen it while on my phone and he says no so I don't think I ever had a notification about it).
Honestly though I can't say that I would've gone to the reception anyway. I was never hugely close to this person, we were in the same friendship group but we weren't best friends and I haven't seen her in a few years. I did know she was getting married but I didn't really expect to get an invitation so didn't think to go looking for one iyswim.
So today I get this horrible message telling me how rude I was for not replying. I went looking for the original message and it is there (complete with present list 
).
I haven't replied to the message. Should I? Aibu for thinking that was not a 'proper' invitation and the fault for this is not mine?
